HENRY F. JEROLAMAN, OF CHICAGO, ILLINOIS, ASSIGlN'OR, BY MESNE ASSIGNMENT S, TO ALFRED H. SMITH, OF CHAPPAQUA, NEW YORK.

RAILWAY CAR.

Application filed August 18, 1921. Serial No.493,440.

To all whom it may concern.

Be it known that I, HENRY F. J EROLAMAN,

' a citizen of the United-States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements, in Railway Cars, of which the following isa specification.

This invention relates to'a novel construction of steel railway cars for the transportation of freightiand: express. matter, and the leading objects of the-invention are to expedite the operations of loading and unloading, to facilitate the handling and dispatch of fractional car loads, and to reduce the height, simplify the construction, and lessen the weight of such .cars. To these and other ends I have designed a car combining'two main novel structural'characteristics;first, an upper-frame or body which rests securely upon, but is unattached to the under-frame, and may bereadily lifted therefrom, or set thereon, by suitable hoist ing apparatus; and, second, a sectional form of such upper-frame or body, which permits the loading and unloading of the sections separately and independently. Other important structural features reside in the interfitting of the bottom of the upper-frame. within andbetwen the side and end sills ofthe under-frame, the restin of the-upper frame directly on the crosscarers or transoms of the under-frame, the further brac-- in of the upper, and under-frames against re ative lateral displacement by vertically s'lidable telescoping members carried by said parts, res ectively, and the construction of the crossearers or transoms of theunderframe in arched form, which both reduces the height and facilitates the interfittingfof the bottom of the 'upper frame between the side sills of the under-frame.

My invention and the advantages secured thereby will be readilynnderstood .when considered in connection with the accompanying drawings, which illustrate one practical form'in which the invention may e embodied, and in which: 1 Fig. 1 is a top plan view of a railway car constructed in accordance'with my inr vention;

Fig. 2 the trucks being conventionally shown,

Fig. 5 is a fragmentary top plan view-0f Fig. 3 is an end elevation on an enlarged.

the under-frame on the same scale as Fig,

ures 3 and t, and s Fig. 6 is a vertical longitudinal section through an end portion of the'car, on the same scale as Figures 3, 4, and 5.

Referringto the drawings, 1

a pair of inwardly facing channels) extending the I house the draft-gear not shown) y secured to the designates the side sills, 2 the center sill (comprising full length of the under-frame and I adapted to at each ,end, and 3 the end sil s; the side I the most part, shown as T-beams', but certain of. them, such as 5 (Fig. 6

- are pref erably- X-beams,'for a purpose ereinafter disclosed. To the underside "of the center plates 9 (Fig, 6), such asare commonly used this case, as it is unnecessary.

. The upper-frame or body ofthecar' is sill 2 is secured, at the-proper points, center on the underside of the usual body-bolster, the latter being preferably dispensed with in 7 as u 11- ving its end, side,

I braced, as" best;

shown in Fig. 6, the bracing ofthe' bottom wall convenientl consisting simply of trans:

. versely dispose angles 11 which rest di .rectly uponand. across the center sill 2 be-' tween the cross bearers 5 and 5!; the bottom- .sudden pullin 'and bufiing shocks, I pro respondingl shaped ribs 13 on the lower longitudina edges of the upper frame, which ribs may conveniently be formed by extending the side walls beneath the floor 14, bending them to proper form, and riveting them to the floor, as shown. This results in the formation of projections which are wedge-shaped in cross section the projections serving to cooperate with the triangular spaces to position the boxes on the frame. With this construction, the upper portions of the side sills and the inclined edges of the cross-bearers cooperate with the ribs in preventing lateral displacement of the upper-frame relatively to the under.

frame.

To prevent relative longitudinal displacement of the upper and under-frames under vide, in addition to the described X-beam form of cross-bearers 5, end posts carried by the under-frame, and, one or more inter mediate posts, 'which are telescopically engaged by" parts carried by the sections of the upper-frame. The end posts referred to are shown at 15 and consist preferably of T- beam sections strongly secured at their lower ends in and to outwardly bent sockets 3* formed in and centrally of the front sills 3, for which purpose the intermediate portion 3 of each front sill 3 is extended upwardly to approximately the full height of the post, the socket 3 extending the full height of the central part ,of sa d intermediate portion; and to further reinforce the said socket I may also apply reinforcing gussetplates 16 riveted to and covering the outer surface of the front sill portions 3 and 3", and also reinforcing gusset-plates ,17 liV? eted to the horizontal flanges of the plate 16, the center sill 2, and the main body portion of the frontsill 3, as clearly shown in' Fi 3 and 5. The post 15 is secured in its soc et by rivets 18. Slidably engaging and cooperating with the inwardly disposed webs of the posts 15- are undercut or dovetail channelistrips 19 (Fig. 3) secured to the outer ends of the end sect1ons'10 of the body or upper-frame. Secured to and projecting upwardly from the central portion of theunder frame, are a pair of intermediate posts 20 (Figs. 1 and 4) of substantially the same form as the end posts 15; said intermediate posts bein conveniently supported and secured in p ace by a suitably reinforced vertical web plate 21, itself riveted to one of the cross-bearers 50f the under-frame. The posts 20 are riveted to each other and to opposite sides of the web-plate 21 by transverse rivets 22; and cooperating with the posts 20 are channel strips 23 secured to the inner ends of the intermediate body sections 10*. 1f desired,'similar connecting devices may be employed between the sections 10 and 10 of the body, but this will depend mainly upon the number of sections into which the complete upper-frame or cara body may be divided in any given case. In a car-body employing four sections, as herein shown, the two'end connections and the single intermediate connection are, in practice, suflicient. 1

Each body-section will be, in practice, provided witha suitable door for opening and closing the same, and I have indicated for this purpose in Fig. 2 the usual slidingdoors 24, but my invention is not concerned with this particular feature of construction.

In the practical use of the car, the same may be loaded and unloaded in the usual fashion through the doorways where the car can be detained for this purpose or where the loading and unloading requires but a limited amount of time. In the principal contemplated use of the invention, however, for the purpose of loading and unloading, each section will be removed at 26 to receive hooks on the hoistin appa- I ratus. In this way, one or more be ed sections. canbe quickly removedfrom the under-frame for unloading, allowing other loaded or empty sections to be immediately replaced upon the under-frame, so that the car canbe released without havingto wait for unloading. As freight cars are frequently delayed many days at" a time by the unloading of thesame, it' will be seen that my invention greatly romotes the prompt handling and dispatc of the cars themselves in service.

It will be noted that the up er and under! frame'are not bolted, riveted: or otherwise securedtogether by fastening means which require to he removed or released before the parts can be separated; the connections being of a purely interfitting or telescopin character, so that the parts can be separated or broughttogether in secure relation to each other by a. simple relatively vertical movement between them.

It will be evident to those skilled in the art that the particular structural details herein. illustrated might be considerably modified and varied without departing from lessons the rinciples involved or sacrificing any of the enefits and advantages secured thereby.-

Hence, I do not limit the invention to the exact construction shown exce t to the extent clearly indicated in-speci c claims.
